RE:Lets be blunt I agree with you, who cares?
More importantly, investors have to decide if the technology is legit and whether it can be commercialized (my opinion is yes). In fact it has been commercialized in some verticals. We know all this so there's no point in detailing here.
Does Pyro have the cash and receivables and opportunities to carry on as a going concern well into 2025 (again, my opinion is yes). Pyro itself confirmed this in year end comments. It also has minimal debt.
As with all stock investments and especially with small cap start ups (and I consider Pyro to be in start up phase in spite of its actual age) you balance risk & reward. But, lets be blunt, you have to analyze the relevant information. Return on equity and return on assets,at this point in time, are ratios that don't provide prospective and existing investors in Pyro with particularly relevant information.
You can spend the time to figure out various ratios from the numbers contained in the financial statements (and I have no idea if yours are correct) but to simply post these ratios and to leave it at that, doesn't inform investors with respect to what's most important to review and discuss when making decisions on investing in Pyro.
You can pick away at these comments, but for me they're just common sense.
